GATE.

SPECIFICATION forming part of Letters Patent No. 403,401, dated May 14,1889. Application filed March 5, 1889. Serial No. 301,921. (No model.)

To all whom it may OOH/06772,:

Be it known that 1, CHARLES TIBBs, a citizen of the United States,residingat Vandalia, in the county of Fayette and State of Illinois,have invented new and useful Improvements in Gates, of which thefollowing is a specification.

My invention relates to improvements in gates; and it consists incertain novel features hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view showing myimproved gate closed. Fig. 2 is a side view of the gate, showing themanner of operating the same.

In carrying out my invention I erect along one side of the road a seriesof posts, A A, which extend in opposite directions from the gateway, andhave a rotary shaft, 0, journaled in their upper ends. This rotary shaft0 is provided at its center with a grooved pulley, D, and at its endswith suitable operating-han dles, E. In the drawings I have shown thesehandles as consisting of disks having radiating arms F but it will beunderstood, of course, that any other suitable form of handle could beemployed.

At one side of the gateway, and between the center posts, A A, I arrangethe fulcrum block or sill G, and to this fulcrum block or sill I pivotthe lower ends of the swinging levers or gate-supports II H. The gate Iis pivotally secured to the upper ends of the swinging levers H, andconsists of the horizontal rails J and the vertical end bars, K, of theusual construction. At the opposite upper corners of the gate I securethe ends of the cables L L, which extend from the corners of the gate upto and over the grooved pulley D, passing each other on the said pulleyand having their ends secured to it at diametrically-opposite points.

The operation of my improved gate is very simple, and, it is thought,will be readily understood. When it is desired to open the gate, theshaft is operated by turning the handle at either end, thereby rotatingthe grooved pulley, so as to draw on the cable secured to the front endof the gate and cause the said cable to lift the gate at its front end.Inasmuch,

however, as the gate is pivoted to the swinging levers, the lifting ofthe end of the gate will cause sufficient force to be exerted againstthe upper end of the swinging levers to raise the said levers and causethem to swing toward the posts, and thus move the entire body of thegate. The shaft is rotated suificiently to bring the upper ends of theswinging levers slightly past the vertical plane of the said shaft, whenthe weight of the gate will carry the levers beyond the said plane andcomplete the opening of the gate. To close the gate the rotary shaft isturned in the reverse direction, as will be readily understood.

From the foregoing description it is evident that I have produced a gatewhich is composed of the fewest possible parts, and is therefore notliable to get out of order, and which can be operated very easily andrapidly by a person on horseback or in a vehicle without the necessityof alighting and while at a distance from the gate.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

1. The combination of the swinging levers,

the gate supported thereby, the pulley arranged above the gate, meansfor operating said pulley, and the cables having their ends secured tothe pulley at diametrically-oppoposite points, extending over the pulleyin opposite directions, and secured to the opposite upper corners of thegate, as set forth.

2. The combination of the transverse sill, the swinginglevers pivoted attheir lower ends to the said sill, the gate pivoted to the upper ends ofthe said levers, the rotary shaft, the grooved pulley secured on saidshaft, and the cables secured to the opposite upper corners of the gateand extending to and over the pulley and secured thereto, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

CHARLES TIBBS.
